Sally Hansen Diamond Strength Instant Nail Hardener Reviews

I honestly cannot believe this got such a low rating. When I used to use this as a topcoat it really hardened my nails and they didn't break half as easily. I would highly reccomend this. It doesn't harden the nails after its removed, though.

I bought this hoping to strengthen my nails but instead found myself frustrated with this product. It would only last 2-3 days before I noticed peeling...arrgh! I've bought other Sally Hansen products with better success-- such as their Nail Protex which I love...guess I'll stick with my original choice--
